Kanetec LMU-UW Waterproof Electromagnetic Lifma
Product Made in Japan
Manufacturer: Kanetec
Model: LMU-UW
Application
Electromagnetic type lifting magnets used as a lifting section of cranes and hoists for transportation of steel materials in underwater work environment as well as outdoor work sites.
Features
- You can use these Lifmas underwater up to 3 atm (equivalent to a maximum water depth of 30 meters).
- Remote operation can electronically control the attraction and release of workpieces.
- Additionally, we require a rectifier.
- Using an uninterruptible power supply ensures safety in case of unexpected power failure. (To study specifications, refer to Model LMU’s holding power graphs and lifting reference.)

- A value that is half of the maximum holding power indicates the lifting capacity.
- For workpieces having poor attractive conditions such as scraps and waste materials, use LM-EC2.
- For continuous operation, use the Lifma at 110 VDC or below. Note that when the thickness of steel plates to lift is 20 mm, the listed lifting capacity drops by approx. 20%.
- The height of lifting part is up to the top end of the inside diameter of the eyebolt.
- Including Cable 2 m.
